The fact has worried many scientists _____ the earth is becoming warmer and warmer these years.
A．whichB．thatC．a(chǎn)sD．what
B

試題分析：考查名詞性從句的同位語從句。本題的That引導(dǎo)同位語從句that the earth is becoming warmer and warmer these years解釋名詞the fact的內(nèi)容，句意：這些年來地球變得越來越熱這個事情讓很多科學(xué)家很擔(dān)憂。That在同位語從句中不充當(dāng)任何成分，只起引導(dǎo)作用。故B正確。
點評：名詞性從句的考查集中在引導(dǎo)詞的選擇上，連接詞that, whether, if在句中不充當(dāng)任何成分，只起連接作用；連接代詞who(ever), which(ever), whom(ever),whose(ever),what(ever)在句中做主語，賓語，表語和定語；連接副詞when, why, where, how，在句中做狀語。應(yīng)從上下句的句法關(guān)系著手分析，切不可‘望句形生答案’總的來說，考生在解答此類型時，可用排除法或造句法，造句法就是仿造原句的語法功能仿造出一個易懂易理解的句子，幫助判斷。
